The iodine clock reaction is a classical chemical clock demonstration experiment to display chemical kinetics in action; it was discovered by Hans Heinrich Landolt in 1886. The iodine clock reaction exists in several variations, which each involve iodine species (iodide ion, free iodine, or iodate ion) and redox reagents in the presence of starch. Two colourless solutions are mixed and at first there is no visible reaction. After a short time delay, the liquid suddenly turns to a shade of … Web22 feb. 2024 · This demonstration is based on the following mechanism: 1. IO 3- (aq) + 3 HSO 3- (aq) --> I - (aq) + 3 SO 42- (aq) + 3 H + (aq) 2. IO 3- (aq) + 5 I - (aq) + 6 H + (aq) --> 3 I 2 (aq) + 3 H 2 O (l) 3. I 2 (aq) + HSO 3- (aq) + H 2 O (l) --> 2 I - (aq) + SO 42- (aq) + 3 H + (aq) 4. I 2 (aq) + I - (aq) + starch (aq) --> starch-I 3- (aq)
